To. all whom t mayconcern:

Be it known that. I, MICHAEL JOSEPH OBRIEN, of the borough of Manhattan, in the city of New York, county of' New York,

and State of New York, have invented an y use of such floors is that, even when concrete or asphalt is used, owing to the expansion and contraction of the flooring -material around the basin or trap, it is difficult to preserve an absolutely tight connection between that material and the trap or basin, the consequence of which has been that the water will seep through the openings and find its way from one floor to the ceiling of the room below, causing inconvenience and oftentimes-great damage. This objection, ,it is one of the objects of my invention to obviate, and the result accomplished by surrounding the basin with a. eculiar construction of cast iron pan, whic is cast as an integral part thereof and which is adapted to act as a receptacle to retain any moisture which may descend between lthe iiooring material` and the basin proper or in near proximity thereto, which moisture either. descends from the pan directly into the drain pipe, below the basin, through the respective passages therefor, or ils'lost by evaporation, depending upon the amount .of water lor molsture present. Y.

Thel basin, pan and the drain pipe which makes connection with Athe pipe leading to the sewer I prefer to cast complete at one op-y eration and in one single structure, with the exception of the grating or cover at the top of the basin which is capable of being removed. In this manner I am enabled to produce a cheap, durable and reliable basin or trap for stable floors which is absolutely water tight and overcomes the disadvantages hereinbefore referred to.

My invention also relates .to a novel and useful means of forming the connection between the hub of the castiron pipe leading from the'basin and the pipe leading to the sewer connection,- which results in much saving of time, labor and consequent eX- lpense, this feature consistingof a cast iron cup having an outlet, which cup is likewise cast as lan integral part of the Sstructure, through which cup an outlet connection is made with the interior of the hub of the cast iron drain pipe, and into which cup molten lead is poured to make the water tight connection between the hub of the cast iron drain pipe and the pipe leading to the sewer connection. l

Figure 1. represents an elevation of the structure in section, through the center thereof, showing the same in .place (in the flooring. Fig. 2. is aplan view of the pan surrounding the basin, which is shown in thecenter of the drawing. Fig. 3. is a side elevation of the complete structure.

Referring to the drawings: A is the basin proper, being located in a slight depression in the flooring D and having square shaped flange portion B projecting horizontally from the top thereof, in or near the center of which flange portion and located in an offset in the top thereofis the grating C. The pan E is of square or rectangular shape and projects' laterally from the outside of the basln at a point near or slightly below the'middle thereof. Said pan E is provided with perendicular flanges eee, the two inner flanges being provided with openings or passages FFFF. Through these openings, owing to the bottom of the pan being slightly elevated from the center toward the outer sides, the water or moisture gravitates toward and into the innermost section of the pan, wherein, at either side thereof, is locatedv an opening G, through which the water passes into the passageway H, and through the 'passageway H',

connecting with tvhe drain pipe I. The upright flanges e, in connection with the horizontal flange B, also serve to embed and -hold the structure firmly in the loorlng material.

It will be readily understood that the main through openings G and passages I-I and H loo l into the drain pipe. I and thenee to the sewer eonneetion.

ln the drawings I have shown the basin of eireular shape and the pan of square or reetangular shape., but it will be apparent that the shape of the basin and pan may be varied as may be desired to suit the conditions oll the installation to be made.

'lhe drain pipe I is shown as a female member having the hub J, and in the easting of the hub it is formed with the eup or opening K eommunieating with the inner portion of the hub. By means thereof I am'enabled to eil'eet the leading of the connecting male member to the hub portion of the female member with great saving ol time and labor and with less ineonvenienee than has heretofore been the praetiee in making sueh eonneetions. It avoids the neeessityY of inverting the pipe and also permits a shorter length ol' eonneeting pipe to be used, as is often desirable. where the eonneeting pipe is to be leaded near the ceiling of the room below. In the praetiee ol' this method the male member, as shown at. li, is inserted into the hub J, a layer of putt)Y and oakum .\l is temporarily ealked into and between the outside of the top or near the top ol' the male member and the inside of the hub, thus lilling the lower part of the spaee between the two pipes, and making a temporarily tight eonneetion between the inside of the bottom of the hub and the outside of the top of the pipe to be eonneetml thereto, or this spaee may be elosed at the bottom only, by means of a eollar or strip of asbestos of the required width. 'l`his having been done, molten lead N is poured through the opening of the, eup K and Iills the lower part oll the opening between thel inside of the hub and the outside. of the pipe to be eonneeted thereto; the molten lead on the inside of the hub rising b v means of gravityv to the level of the molten lead in the eup K, and when the lead has become eool the eonneetion is eomplete and perfect, after which the temporar)T stopping of putty and oakum or asbestos is removed.

What I elaim as my invention and desire to seeure by lait-ters Patent, is:

1. A floor drain, having a basin open at the top of the loor and means extending outward below the top of the basin having eonneetion with said basin to earry baek liquid pertailating through the lloor.

2. A lloor drain, having a draining means open at the top ofthe lloor and a pan extending outward below the top of the draining means and diseharging into the same.

3. In a lloor drain, the. eombination with the floor of a draining means extending through the loor and open at the top thereol, and means extending outward from the draining means under the floor having eonneetion with said draining meansto earrv bat-k liquid pereolating through the loor.

4. In a tloor drain, the combination with the Iloor oll a draining means extending through the floor and open at' the top thereof, and a pan ext-,ending outward from the draining means under the floor having eonnection with said draining means to carry baek the liquid pereolating through the floor, said pan having interrupted llanges projecting upward into the lloor.
